build-up in the drop tube
(Figure 16.3)
.
c. Assemble the crevice tool from the micro cleaning
kit to attach to a Shop Vac

exits at the back of the firebox floor (left and right)
be thoroughly cleaned
(Figure 16.2)
. There are
several ways this can be done:
— Use the crevice tool.

the bottom. Remove the combustion (exhaust)
blower and then vacuum out the ash.
